Intercellular junctions are specialized structures that connect adjacent cells and regulate the properties of intercellular spaces. Key types of intercellular junctions include:
Tight Junctions: These junctions create a seal that prevents the free passage of substances between cells, thereby minimizing intercellular spaces. Adherens Junctions: These junctions provide mechanical stability by linking the actin cytoskeletons of neighboring cells. Gap Junctions: These channels allow the direct exchange of ions and small molecules between cells, facilitating cell communication.
